Oh dismal mourning...
I open my weary eyes once again
My life has been left hollow and ashes have filled the gorge of my within
Last night I hoped and wished I'd die in my sleep but no catharsis was granted to
me
Will this pain ever pass?
The enchanting perfume of winter and the bleak, cold breath of her still haunts
me...
Oportet ubique pulchritudinem evanescere

So half of me rode to the mountains and the other half soared high in the winds
to a place where the angels had fallen, the soil gagged and choked on their wings
My soul was the pale skyline that she stretched across the horizon
Two years had brought the fire that she paints upon my loathsome canvas

She is the dark one...
As a bird I watched her from my cold tower in the heavens
and when she fell from the northplace, I flew down and embraced her
I took her where the snow falls forever, she showed me the haunted woods
We gathered together in the oaken palace, free from both death and life
The fire blazed in her eyes one day and she tore the soul from my chest
With a bleeding heart, I flew back to my cold tower
to never escape and lie in a pool of death forever

I saw the nightfall...
It called to me like a river of shadows
It sang to me with the cries of a thousand ravens that blackened the sky as they
took flight
and sank the Sol
I shall never trust the sun again, Eridanis Nadir

I ran away far into the woods
To find the Sol, I called to her...
"I don't want to be forgotten...I never wanted to be human"
NEVER!!!!!

So alas the sun had descended, her fire burned brilliant in the sky
The trees bore their withered silhouettes, that cast a spell upon unearthly white
No wolf shall keep his secrets, no bird shall dance the skyline
And I am left with nothing but an oath that gleams like a sword
To bathe in the blood of man
Mankind...

it is seemingly about a girl who he thought was the one for him. The first part of the song is almost like showing the aftermath of her. The second part then shows how beautiful the time spent between him and her were, but then she betrayed him somehow. The third part is a loathsome denouncing of her, which in turn segues back into where part one begins. The whole thing sorta loops.
